SOFFIT CLIP FO'R REENFORACED CONCRETESTRUCTURES.

i Application filed March 2, 1922. Serial No. 540,394.

T 0 all whom it may concern Be it known that I, HERBERT G. OLIVER, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Sofiit Clips for Reenforced Concrete Structures, of which the following is a full, clear, and exact description.

This invention relates to clips and in particular to the type known as sofiit clips which are used to maintain a reinforcing structures filed January 23, 1922, Serial No. 531,114, to which cross reference is here made.

A further object is to provide clips which may be caused to grip the edge of the beam flange and thereby prevent movement ofthe wires or reinforcing agents when the concrete is poured and tamped therearound.

Drawings.

Figure 1 is a bottom plan view of astructural beam having applied thereto a clip which comprises a means for causing the clip to resiliently grip the edges of the beam, the beam being shown in outline.

Figure 2 is a view similar to Figure 1 and shows the use of a sleeve member in conjunction with the clip members.

Figure 3 is a view similar to Figure 1 and shows a single piece clip which is automatically adjustable to various widths of beams Figure 4 is a view similar to Figure '1 showing the application to a beam of a clip made in three parts and also adjustable to fit various widths of beams, where a single reinforce is used.

Figure 5 is a view similar to Fig. 1 and illustrates the use of sleeves in conjunction with the cli elements.

Figure 6 is a view similar to Figure 4t showing the use of an expandible clip as used with a single reinforce. t

Figure 7 is a view similar to Figure 2 and illustrates the use of a loop connection between the clip elements.

Figure 8 is a view similar to Figure '7,

the reinforce wires being replaced by a metal ribbon which may be expanded metal and through which the clips may extend.

Figure 9 .is a section taken on the line 99 of Figure 8 showing the method of allowing for the passage of the clips through the ribbon-like reinforce element.

Description.

In the drawings, and for convenience of illustration, Figures 1, 2, 3 and 7, are re ferred to collectively, the under side of a structural element or beam 10 has associated therewith and in spaced, relation thereto the longitudinally extending reinforcing wires 11 which have extended transversely thereof the soiiit clips 12. The clips are spotwelded to the wires 11 at the points 13 where they cross each other, and the loops 142 formed therein and disposed adjacent the edges of the beams 10 provide spacers through the medium of which the reinforcing elements 11 are maintained at suitable distances from the faces of the beams. The free ends of the loops'l i, not shown, are bent over the edges of the beams to hold the clips in position, all as fully described in 'my co-pending application referred to.

In said application, the clip was held against the edge of the beam fixedly by the tension exerted by spreading the reinforcing wires at the point where they were attached to the clips. This prevented any movement of the reinforcing wires or clips when being put in place or when the concrete filling was applied about the beam.

In order to provide for the fixing of the wires and clips in cases where two or more substantially parallel wires are used, it is 7 very necessary that the clips 12 be free enough to. be applied by hand to the beam and subsequently tightened up to insure against movement of either wires or clips when the concrete is poured and tamped.

In Figure 1 the clip 12 comprises a single.

piece of wire at the center of which is formed the extended loop 15 over which may be passed a wire sleeve 16. When the clip is applied to the beam the legs of the loop 15 are distended depending upon the width of beam. 1 When the sleeve 16 is therefore forced over the loop it will draw. on the clip ends and tighten them on the beam.

In Figure 2 the clip comprises bent ends 17 which are held in sliding relation with End each other by a sleeve 18 which passes therearound, and which when pinched holds the clip ends 17 in fixed relation and the clip securely against the beam edges.

A loop. 18 formed in the clip and disposed intermediate the wires 11 provides a means of retaining the clips in place, as it, being resilient tends to draw the loops of the clips inwardly, as shown in Figure 3.

In Figure 7, the ends 19 of theclips are looped to engage each other, and in the space provided between the loops, a tool may be inserted .to expand the ends 19 at that point, thus causing the clips to grip the edges of the beam.

When it is necessary to use only one reinforce wire 11, provision is also made for holding the clips to the beam edges and as illustrated in Figure at, a separate piece of wire 20 is welded to the wire 11 transversely thereof and its looped ends engage the looped ends of the clips, thereby leaving va 7 space through which as explained in reference to Figure 7, the wire 20 and clip ends may be distended to draw the loops slightly inward or until they tightly grip the beam edges. 7

A similar piece of wire may be used, see Figure 5, and may be associated with the clip ends by sleeves 21, which when pinched hold the clips in fixed relation with the edges of the beam.

In Figure 6 a loop 22 is formed in the clip 12 and is attached to the wire 11 by a,

welding 13. In Figures 8 and 9 ribbon like reinforcing elements 23 are illustrated, in place of wires, which are provided with longitudinal slots 24. The free ends of the clip are passed respectively through. the slots and terminate therebeyond in the bent portions 25.

Claims.

the grip of the same on the edge of the element.

3. The combination with a structural element, of a reinforcing member spaced therefrom, and a multi-part clip cooperative with said member and adapted to engage the edges of said structural element, the parts of said clip being extensible to fit various v widths of structural elements;

a. The combination with a structural element, of a reinforcing member extending longitudinally thereof, clip members cooperative with the reinforcing members and adapted to engage the edges of the structural element, means formed on said clip members for holding the reinforcing members in spaced relation to the structural elements, and means cooperative with said clips for causing contraction thereof when the same have been abnormally expanded.

5. The combination with a structural element, of a reinforcing member extending longitudinally of said element, clip members each formed of relatively adjustable parts for supporting said reinforcing element and adapted to engage the opposite side edges of said structural element, means formed with said clip members for maintaining said reinforcing member in spaced relation to the structural element, and means cooperative with the parts f said clip members for retaining the same in operative engagement with said structural element.

6. The combination with a structural ele ment, of a reinforcing member extending longitudinally of said element, clip members in independent and relatively adjustable connection with said reinforcing member and adapted to engage the opposite side edges of said structural element, and means cooperative with the parts of said clip members for retaining'the same in operative engagement with said structural element.

7. The combination with'a structural ele-- ment, of a longitudinal reinforcing member, and a means carried by said member and adapted to engage the opposite sides of said element to secure the member in position thereon, said means being adjustable by extension for engagement with elements of various widths.

8. The combination with a structural element, of longitudinal reinforcing members extending parallel to each other and to said structural element, means connecting said reinforcing members together adjustably, and extensibly adjustable means cooperative with said connecting means for attaching said reinforcing members to said structural element.
